Objective Together with the nitro PAHs, the oxygenated derivatives are considered to be amongst the major sources of potential carcinogens. More than 50 oxygenated PAHs have been detected, eg in the gaseous effluents from the combustion of brown coal briquettes. PAHs present in drinking water may react with ozone to form oxidized compounds if the conditions of ozonation used for the purification of water are not well controlled. The preparation of a limited number of pure oxygenated PAHs has been undertaken because such compounds are not readily available elsewhere. RESULTS The purity of 7 oxygenated PAHs have been certified as follows: - CRM 337: Dibenzo(b,d) furan 99.0% - CRM 338: 4H-Cyclopenta(def)phenanthrene-4-one 99.58% - CRM 339: 6H-Benzo(c,d)pyren-6-one 98.9% - CRM340: Benzo(b)naphto(1,2-d)furan 99.7% - CRM341: Benzo(b)naphto(2,1-d)furan 99.64% - CRM342: Benzo(a)fluorenone 99.79% - CRM 347: 3-Hydroxybenzo(c)pyrene 99.4% Fields of science engineering and technologyenvironmental engineeringwater treatment processesdrinking water treatment processesengineering and technologyenvironmental engineeringenergy and fuelsfossil energycoalnatural scienceschemical sciencesorganic chemistryhydrocarbons Programme(s) FP2-BCR 4 - Research and development programme (EEC) in the field of applied metrology and chemical analysis (Community Bureau of Reference - BCR), 1988-1992 Topic(s) Data not available Call for proposal Data not available Funding Scheme CSC - Cost-sharing contracts Coordinator FEDERAL INSTITUTE FOR MATERIAL RESEARCH AND TESTING Address 87,unter der eichen 87 12205 Berlin Germany See on map EU contribution € 0,00 Participants (11) Sort alphabetically Sort by EU Contribution Expand all Collapse all Biochemisches Institut für Umweltcarcinogene Germany EU contribution € 0,00 Address Sieker landstraße 19 22926 Ahrensburg See on map Centre d'Etudes et Recherches des Charbonnages de France (CERCHAR) France EU contribution € 0,00 Address 60550 Verneuil-en-halatte See on map Consiglio Nazionale delle Ricerche (CNR) Italy EU contribution € 0,00 Address Roma See on map Head of the Unit of Foodborne Zoonoses and Veterinary Epidemiology Italy EU contribution € 0,00 Address Viale regina elena 299 00161 Rome See on map Links Website Opens in new window INSTITUT CURIE France EU contribution € 0,00 Address See on map Links Website Opens in new window Microtest Research Ltd United Kingdom EU contribution € 0,00 Address Heslington YO1 5DD York See on map National Physical Laboratory (NPL) United Kingdom EU contribution € 0,00 Address Queen's road TW11 0LW Teddington See on map Riso National Laboratory Denmark EU contribution € 0,00 Address See on map Studiecentrum voor Kernenergie Belgium EU contribution € 0,00 Address Mol See on map TNO-ITC Netherlands EU contribution € 0,00 Address Zeist See on map Union Technique de l'Automobile du Motocycle et du Cycle France EU contribution € 0,00 Address Autodrome de linas 91310 Monthlhéry See on map
